IMPROVEMENT IN PEDESTALS FOR RAILROAD-CARS.

` Specification forming part of Letters Patent No. 50,4127, datedOctober 10, 1865.

To all whom it may concern Be it known that we, ISAAC P. WENDELL andSTEPHEN USTICK, of the city and county of Philadelphia, and State ofPennsylvania, have invented a new and useful Improvement in Bailroad-Cars 5 and we do hereby declare that lthe following is a full, clear,and exact description ofthe construction and operation of the same',reference bein g had to the annexed drawings, making a part of thisspeciiication,

in which- Figure I is a perspective view of the improved pedestal. Fig.2 is a vertical section of the same. Fig. 3 is a horizontal section atthe red line a b of Fig. 2. Fig. 4 is a perspective view of acushion-plate, E. Fig. 5 is an end view of one of the adjustablefacings, B. Fig. 6 is a side view of the same. Fig. 7 is an end view ofone of the adjustable facings, B'. Fig. Sis a side view of the same.Fig. 9 is a single plate for a facing,ona diminished scale.

Like letters in all the iigures represent the sameparts.

The nature of our invention consistsin combining adjustable facings withthe vertical arms of pedestals, between which the journalboXes ot'railroad-cars are situated, to compensate for the wear occasioned by thevibration ofthe boxes, the said facings being constructed and arrangedin the following manner.

A is a pedestal, which has vertical arms a a', between which thejournal-boxes usually slide in the springing of the car. On each of thearmsawe place eXtension-facin gs, B and B', so constructed and arrangedthat they may be set inward toward the bearing sides of the journal-box,and outward toward the flanges or lips of the same, to compensate forthe wear occasioned by the vibrations of the journal-box during thespringing of the car. The adjustment of the said facings we accomplishby means of the conically-pointed screws C C in the arm a, which arescrewed up to expand the facings and unscrewed to slacken the same, theconical points b b fitting in corresponding holes c c in the joint-edgesof the facings. There is a screw, D, in the arm a, midway between th'escrews G C, for the purpose of conining the plates B and B' against theconical ends of the screws C C, as represented in Figs. l and 2, thepivot end of the screw, as represented in Fig. 2,tting in thelugdoftheplate B', by which means'the plate is pressed against theflange e, (see Fig. 2,) thereby causing said screw to act equally oneach plate. Thefacings B and B are represented in detail in Figs. 5, 6,7, and 8.

E E are cushionp1ates,which are interposed between the arms a a of thepedestal and the respective extension-plates B B', and B B', to preventa rigid vibration ot' the journaLboX, there being holes fff in eachstrip, through which the screws C, C, and D pass freely. rIhe saidstrips are made of india-rubber or other compressible elastic substance.

Instead of having a single plate extending along the whole side or innerface of the combined facing B and B', two or more strips may be used,with space between them, in which case it will be most convenient toplace them vertically.

Instead of expanding the plates B and B' by means of the conical screwsCC, we contemplate adopting sometimes the following equivalents, viz: Weconstruct a dovetail wedge, F, (represented byred lines in Figs.5,6, 7,and 8,) by which the plates B and B' are spread apart, to take up thewear of their edge and that of the ianges of the journal-box. The saidplates in this case are confined by means of screws on the packing.

Instead of placing the wedge F between the edges ofthe plates B and B',it may be put betweenthe flange of one ot' them and the contiguous edgeof the pedestal-arm a. Instead of using the metal strips, the outeredgesofthe packing may be turned over the edges of the arms a a.Themetallicdovetailstrip or wedge F may be operated by a screw whichpasses through the bottom plate, G, of the pedestal.

Having thus full y described the construction and operation ofourimprovement in pedestals for railroad-cars, what we claim therein asnew, and desire to secure by Letters Patent, is-

1. The eXtcnsion-platesBandB', constructed and arranged in relation tothe arms a a. ot' the pedestal and the jonrnal-box between the same, forthe purpose of taking up the wear occasioned by the sliding of the saidbox, substantiallyin the manner hereinbeforedescribed.

2. Combining the adjusting conically-pointed screws C C with the arms a,of the pedestal and the extension-plates B and B', in eonjunc- Intestimony that the above is our invention with the screw D, they beingarranged tion We have hereunto set our hands and seals. and operatingsubstantially in the manner ISAAC P WENDELL [L s l and for the purposeset forth.

3. The combination of the cushion-strips E STEPHEN USTICK [1" S-l withthe arms a of the pedestal and the exten- Witnesses: sion-plates B andB', substantially as described, and for the purpose specified.
